However, challenges such as drug resistance, systemic toxicity, and poor targeting necessitate innovative approaches. Peptides have gained attention in cancer therapy due to their specificity, potency, and ability to modulate various biological pathways. Peptide-based drugs can act as hormones, enzyme inhibitors, or targeting ligands, contributing to their versatile role in cancer treatment. However, peptides face several challenges, including instability, rapid degradation, and poor bioavailability. One promising strategy is the use of niosomal delivery systems for peptidebased therapies. Niosomes, which resemble liposomes in structure, are vesicles based on nonionic surfactants. They are composed of a bilayer created through the self-assembly of non-ionic surfactants in water, enabling them to encapsulate hydrophilic, lipophilic, and amphiphilic drugs. Their unique properties, such as biocompatibility, biodegradability, and ability to encapsulate diverse therapeutic agents, make them suitable for drug delivery applications. This review aims to explore how the niosomal preparation of peptides can revolutionize oncology drugs by overcoming critical challenges like drug resistance, systemic toxicity, poor targeting, instability, rapid degradation, and low bioavailability.

Here, we describe a roadmap towards the identification and validation of conserved T cell epitope regions from Viral Families of Pandemic Potential (VFPP). For each viral family, we select a prototype virus, the sequence of which could be utilized in epitope identification screens. Examples of viral families considered and their respective prototypes (species/ subspecies) are Coronaviridae (Severe Acute Respiratory Syndrome-related Coronavirus/ SARS-CoV-2), Flaviviridae (Dengue virus/DENV2), Togaviridae (Chikungunya virus/ CHIKV), Paramyixoviridae (Morbillivirus/measles), Arenaviridae (Mammarenavirus/ Lassa), and Picornaviridae (Enterovirus C/poliovirus). The peptide sequences encoded in each prototype virus are then analyzed to determine their conservation across different viral taxonomic groups and viral variants derived from each of the VFPP. We outline available methodologies for epitope discovery based on panels of overlapping peptides and bioinformatics- based predictions of HLA-peptide binding, along with high-throughput in vitro assays, with emphasis on addressing coverage of the general worldwide population. Validation can be achieved by a variety of methodologies, including determining HLA restriction and recognition in samples from volunteers convalescent from previous infections or immunized with approved or experimental vaccines, and immunophenotyping of responding T cells. The capacity of these regions to induce crossreactive T cell responses can be tested experimentally with homologous peptides derived from the various viral species of interest. Importantly, they could be considered as a component of pan-viral family vaccines.
